There is an application which is used for taking surveys. I want to use REST api and add some questions to the survey. So basically I want to update some pages of the survey. Here are the links of that application.
My surveys name is trial and the page number that I want to update is 2.
fields#updateobject
Here is my code to do. But i think the http call I have used is not correct. and I am not able to figure out how to make the request.
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Net.Http;
using System.Net.Http.Headers;
namespace ConsoleApplication1
{
class Program
{
private static object post;
private static object response;
static void Main(string[] args)
{
RunAsync().Wait();
}
static async Task RunAsync()
{
string webReq = "https://restapi.survey.com/v4/survey/trial/surveypage/2?_method=POST?api_token="/*token goes here*/;
// $.post{webReq};
}
}
}
Use System.Net.Http.HttpClient class for sending requests to any API. Tutorial and examples on sending various requests (GET, POST, etc.) can be found here.

I'm working with C# xamarin forms android and I'm trying to get the IMEI number. I've been searching about it and everything I found doesn't works. Now I'm trying with this code but again, Doesn't works.
Errors:
The name settings does not exist in the current context.
The name Forms does not exist in the current context.
C# code:
[assembly: Xamarin.Forms.Dependency(typeof(UniqueIdAndroid))]
namespace AppMobile.Models
{
public class UniqueIdAndroid
{
public string GetIdentifier()
{
return Settings.Secure.GetString(Forms.Context.ContentResolver, Settings.Secure.AndroidId);
}
}
}
Somebody knows how could I resolve this or knows other solution? Thank you very much!
UPDATE 1
c# code:
using Android.OS;
using AppMobile.Models;
using System;
using System.Collections.Generic;
using System.Text;
using static Android.Provider.Settings;
using Android.Provider;
using Xamarin.Forms;
[assembly: Xamarin.Forms.Dependency(typeof(UniqueIdAndroid))]
namespace AppMobile.Models
{
public class UniqueIdAndroid : IDevice
{
public string GetIdentifier()
{
return Settings.Secure.GetString(Forms.Context.ContentResolver, Settings.Secure.AndroidId);
}
}
}
I have added the IDevice interface that I don't know really what it should be and I fixed the settings problem with using Android.Provider;.
this link shows that I have to call with this:
string deviceIdentifier = DependencyService.Get<IDevice>().GetIdentifier();
But i don't understand how to implement IDevice interface.
Someone can help me? Thank you very much!
UPDATE 2
so, now I can use the function.
C# code:
using Android.OS;
using AppMobile.Models;
using System;
using System.Collections.Generic;
using System.Text;
using static Android.Provider.Settings;
using Android.Provider;
using Xamarin.Forms;
using Android.Content;
[assembly: Xamarin.Forms.Dependency(typeof(UniqueIdAndroid))]
namespace AppMobile.Models
{
public class UniqueIdAndroid
{
public string GetIdentifier()
{
//return Settings.Secure.GetString(Forms.Context.ContentResolver, Settings.Secure.AndroidId);
return Settings.Secure.GetString(Android.App.Application.Context.ContentResolver, Settings.Secure.AndroidId);
}
}
}
My problem is that this doesn't give me the IMEI. Insted it gives me the ID of the phone, ¿is there some way to get the IMEI string? Thank you very much!
You can try the following code:
Android.Telephony.TelephonyManager mTelephonyMgr;
mTelephonyMgr = (Android.Telephony.TelephonyManager)Android.App.Application.Context.GetSystemService(Android.Content.Context.TelephonyService);
string imei = mTelephonyMgr.GetMeid(0);
And from android document getMeid, we know that :
Starting with API level 29, persistent device identifiers are guarded
behind additional restrictions, and apps are recommended to use
resettable identifiers (see Best practices for unique identifiers).
This method can be invoked if one of the following requirements is
met:
If the calling app has been granted the READ_PRIVILEGED_PHONE_STATE permission; this is a privileged permission that can only be granted
to apps preloaded on the device.
If the calling app is the device owner of a fully-managed device, a profile owner of an organization-owned device, or their delegates
(see DevicePolicyManager.getEnrollmentSpecificId()).
If the calling app has carrier privileges (see hasCarrierPrivileges()) on any active subscription.
If the calling app is the default SMS role holder
Note:
In general, you can't get READ_PRIVILEGED_PHONE_STATE permission. It's only available to privileged system apps. Unless this is a personal app and you have a rooted device so you can make your app a privileged system app.
For more information, you can check document getMeid.
I'm using Visual Studio Code to develop an Azure Durable Function, following some online examples. I'm completely new to Azure and adapting to C# from VB.NET. I already developed a working durable function that stores data in a blob table. This is a slight adaptation of that which aims to put the information into a queue.
I'm following the instructions here, and have code that I think should work, except that it tells me this:
Cannot apply attribute class 'Queue<T>' because it is generic
However I've looked at some other examples, including the one from Microsoft, and don't anything special being done for typing of queue. Clearly, though, I'm missing something.

using System.Collections.Generic;
using System.Net.Http;
using System.Threading.Tasks;
using Microsoft.Azure.WebJobs;
using Microsoft.Azure.WebJobs.Extensions.DurableTask;
using Microsoft.Azure.WebJobs.Extensions.Http;
using Microsoft.Azure.WebJobs.Host;
using Microsoft.Extensions.Logging;
using Newtonsoft.Json;
using Microsoft.AspNetCore.Mvc;
namespace Test.Groove
{
public static class GrooveWebhook
{
[FunctionName("GrooveWebhook")]
public static async Task<List<string>> RunOrchestrator(
[OrchestrationTrigger] IDurableOrchestrationContext context)
{
var outputs = new List<string>();
GrooveItem data = context.GetInput<GrooveItem>();
string res = await context.CallActivityAsync<string>("AddToQueue", data);
return outputs;
}
[FunctionName("AddToQueue")]
public static async Task<String> Run(
[ActivityTrigger] GrooveItem trans,
[Queue("incoming-groove-webhooks")] IAsyncCollector<GrooveItem> GrooveData,
ILogger log)
{
await GrooveData.AddAsync (trans);
return $"Added Groove transaction for {trans.firstname} {trans.lastname}: {trans.email}";
}
[FunctionName("GrooveWebhook_HttpStart")]
public static async Task<HttpResponseMessage> HttpStart(
[HttpTrigger(AuthorizationLevel.Anonymous, "get", "post")] HttpRequestMessage req,
[DurableClient] IDurableOrchestrationClient starter,
ILogger log)
{
// Function input comes from the request content.
var data = await req.Content.ReadAsAsync<GrooveItem>();
string instanceId = await starter.StartNewAsync("GrooveWebhook", data);
log.LogInformation($"Started Groove webhook orchestration with ID = '{instanceId}'.");
return starter.CreateCheckStatusResponse(req, instanceId);
}
}
}
Now, here's the really weird part. I followed along literally step by step with their http trigger example, code as follows, and yet don't have that same error:
using System;
using System.IO;
using System.Threading.Tasks;
using Microsoft.AspNetCore.Mvc;
using Microsoft.Azure.WebJobs;
using Microsoft.Azure.WebJobs.Extensions.Http;
using Microsoft.AspNetCore.Http;
using Microsoft.Extensions.Logging;
using Newtonsoft.Json;
namespace My.Functions
{
public static class HttpExample
{
[FunctionName("HttpExample")]
public static async Task<IActionResult> Run(
[HttpTrigger(AuthorizationLevel.Anonymous, "get", "post", Route = null)] HttpRequest req,
[Queue("outqueue"),StorageAccount("AzureWebJobsStorage")] ICollector<string> msg,
ILogger log)
{
log.LogInformation("C# HTTP trigger function processed a request.");
string name = req.Query["name"];
string requestBody = await new StreamReader(req.Body).ReadToEndAsync();
dynamic data = JsonConvert.DeserializeObject(requestBody);
name = name ?? data?.name;
string responseMessage = string.IsNullOrEmpty(name)
? "This HTTP triggered function executed successfully. Pass a name in the query string or in the request body for a personalized response."
: $"Hello, {name}. This HTTP triggered function executed successfully.";
return new OkObjectResult(responseMessage);
}
}
}
So then, as if that wasn't weird enough, I went back to my original project that added data to a table, and just added this little queue binding statement, and I don't have the error! This is so crazy. Code begins:
using System;
using System.Collections.Generic;
using System.IO;
using System.Net.Http;
using System.Threading.Tasks;
using Microsoft.Azure.WebJobs;
using Microsoft.Azure.WebJobs.Extensions.DurableTask;
using Microsoft.Azure.WebJobs.Extensions.Http;
using Microsoft.Azure.WebJobs.Host;
using Microsoft.Extensions.Logging;
using Microsoft.AspNetCore.Mvc;
namespace Company.Function
{
public static class GrooveOrchestrationTest
{
[FunctionName("GrooveOrchestrationTest")]
public static async Task<List<string>> RunOrchestrator(
[OrchestrationTrigger] IDurableOrchestrationContext context,
[Table ("GrooveData")] IAsyncCollector<GrooveItem> GrooveData,
[Queue ("GrooveQueue")] IAsyncCollector<GrooveItem> GrooveQueue)
There are no additional using directives in either of the latter solutions that successfully bind the queue for output.
One Additional Thought
I created another version from scratch with the exact same problem, even though my other one is still fine. I have no explanation for this. However, I will note that they are connected to DIFFERENT Azure accounts. Both are on the free tier, both just signed up in the last couple of days. I can't fathom why that should matter, but it's all I can think of.
This problem is caused by the following reference added automatically by VS Code into the .csproj file:
<PackageReference Include="Microsoft.NET.Sdk.Functions" Version="3.0.7" />
This is confirmed by changing it to match the reference from the other solution where the exact same code works perfectly:
<PackageReference Include="Microsoft.NET.Sdk.Functions" Version="3.0.3" />
With this change in reference, it works as expected.
What lead me to this is the fact that my queue binding worked fine when pasted into my older solution from just a few days ago, but the exact same code didn't work in the new solution. To ensure all things were equal, I pasted the entire contents of the .cs file so there would be no difference. I.e. the old solution and the new one had identical .cs files, but one worked and one didn't.
Since my code was identical in both solutions, it seemed clear that there must be something that VS Code had done behind the scenes. I did a stare-and-compare on all its automatically generated files between the old solution and the new one. I discovered that this one reference is literally the only difference between the two solutions, and when I change it to the older version, things work beautifully.
I'll reference the older package for now so I can get this done, and then when I get some free time figure out how to make the new SDK.Functions happy.
You might be lacking reference to Microsoft.Azure.WebJobs.Extensions.Storage.
I'm new in web api and I wrote a code in which I return a datatable in an IHttpActionResult and I want to know what is the difference between return a datatable and a list or dictionary.
this is my code:
using System;
using System.Collections.Generic;
using System.Linq;
using System.Net;
using System.Net.Http;
using System.Web.Http;
using WebApplication2.BLL;
namespace WebApplication2.Controllers
{
public class HomeController : ApiController
{
public IHttpActionResult getpro()
{
var tabla= new Conexion().table();
tabla.TableName = "tablilla";
return Ok(tabla);
}
}
}
I am testing this in post man and is runing well, but I want to know if should I sent a list in the response or another object.
There might not be an apparent difference right now, but as your application grows, you might run into maintainability issues.
The issue is that right now, the signature of your API endpoint (i.e. what data it returns) is hard coupled to your database, so if you change your database, so does the result returned by your endpoint. That's usually a bad thing for anything but the smallest/simplest applications, since it might break consumers of your API.
What you'd do instead, is create models specifically for returning from your API endpoints and then convert (also called map) your datatable to a list of these "view"-models. This way, you can change the backend of your web API without it (immediately) having an impact on your frontend (or other consumers of your API).
I have added a web reference (WSDL) to a class library and then referenced that dll in a timer-triggered c# Azure function (read more about azure functions). The class library has a class EmployeeService which calls a method from the web service (sort of a webservice wrapper). When I call the class lib method (GetEmployees) from a console application, it authenticates to the web service and returns result but when I run the azure function for the same code and creds it returns 401. Not sure what I am doing wrong here :
#r "MyConsult.Service.dll"
#r "Newtonsoft.Json.dll"
using System;
using System.Collections.Generic;
using System.Diagnostics;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Timers;
using Newtonsoft.Json;
using System.Net;
using MyConsult.Service.Service;
public static void Run(TimerInfo myTimer, TraceWriter log)
{
log.Info($"C# Timer trigger function executed at: {DateTime.Now}");
try
{
EmployeeService _empService = new EmployeeService();
var emps = _empService.GetEmployees();
int count = emps.Where(x => !string.IsNullOrEmpty(x.Email)).Select(x => x.Email).Distinct().Count();
log.Info($"employee count : {count}");
}
catch (Exception ex)
{
log.Info($"Exception Message: {ex.Message}");
log.Info($"Exception Stack Trace: { ex.StackTrace}");
}
}
Your console application is likely authenticating based on service configuration settings in your app.config. For your function, you'll need to programmatically apply those settings when constructing the client/proxy.
I am facing a strange imtermittent issue with Azure AD authentication.
We are using CORS enabled web api in our project (origins are specified in web.config which are fetched by custom attribute, and this attribute is used for controllers).
Athorization part is done using adal.js
code is as follows:
startup.cs
using Microsoft.Owin;
using Owin;
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
[assembly: OwinStartup(typeof(test.testapi.WebApi.Startup))]
namespace Test.testapi.WebApi
{
public partial class Startup
{
public void Configuration(IAppBuilder app)
{
ConfigureAuth(app);
}
}
}
Startup.auth.cs
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Security.Claims;
using Microsoft.Owin.Security.ActiveDirectory;
using System.Configuration;
using Owin;
using System.Net;
namespace test.testapi.WebApi

//Following line is not required if you are using HTTPS calls to APIs
//ServicePointManager.ServerCertificateValidationCallback += (sender, cert, chain, sslPolicyErrors) => true;
app.UseWindowsAzureActiveDirectoryBearerAuthentication(
new WindowsAzureActiveDirectoryBearerAuthenticationOptions
{
Audience = ConfigurationManager.AppSettings["ida:Audience"],
Tenant = ConfigurationManager.AppSettings["ida:Tenant"],
});
}
}
}
When the control goes to startup.auth.cs it gives System.Net.Http.HttpRequestException

Now thing is while i was working on my local dev environment i never got this issue(always authenticated fine ) but QA was facing this issue on QA server, so we started hosting web api from my machine, After which i also started getting this issue and that too quite frequently now.
what is this issue if anyone has faced this same issue.
